CYRUS MOORE AND PERRY SAVILLE WEST, OF PERRY, MICHIGAN; SAID VESTASSIGNOR TO SAID MOORE.

AUTOMATIC FRICTION-GOVERNOR.

SPECIFICATION forming part of Letters Patent No. 600,497, dated March 8,1898.

Application filed May 11,1897. Serial No. 636,020. (No model.)

To all whom, it may concern:

Be it known that we, CYRUS MOORE and PERRY SAVILLE EST, of Perry, in thecounty of Shiawassee and State of Michigan, have invented a new andImproved Automatic Friction-Governor, of which the following is a full,clear, and exact description.

The object of the invention is to provide a new and improved governorwhich is simple and durable in construction, very effective andautomatic in operation, and designed for use on windmills, engines, andother machines and apparatus.

The invention consists principally of a friction-rim, one or morebrake-blocks adapted to move in engagement with the inside of the saidrim, levers fulcrumed on a wheel turning with the shaft or other movablepart of the machine on which the device is used, and a loosespring-pressed device connected with the said levers to cause the sameto swing simultaneously inward or outward.

The invention also consists of certain parts and details andcombinations of the same, as will be fully described hereinafter andthen pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is a side elevation of the improvement. Fig. 2 is a transversesection of the same. Fig. 3 is a face view of part of the rim. Fig. 4 isa perspective View of the diskarm. Fig. 5 is a perspective view of thetension device for the disk. Fig. 6 is a side elevation of theconnecting-rod between the disk and levers, and Fig. 7 is an enlargedperspective view of one of the brake-blocks.

On the shaft A or other movable part of the machine on which the deviceis applied is secured a wheel B, on the web of which are fulcrumed at Oa series of levers O, each carrying at or near its free end a weight D.Each of the levers O is pivotally connected by a link E with abrake-block E, arranged close to the inner surface of a rim 1?, havinglugs F for fastening the said rim to a support, such as the frame orother stationary part of the Each brake-block E is pivotally connectedby a link E with the wheel B, so that the blocks are held in properposition in notches cut in the rim or web of the wheel B. The free endof each lever O is pivotally connected by a rod G with a .disk H,mounted to rotate loosely either on the shaft A or on the hub of thewheel B, as illustrated in the drawings, and on the said disk II issecured an arm H, pivotally connected with a tension device, consistingof a rod I, pivoted on the arm H and fitted to slide near its outer endin a bearing .I, attached to the wheel B. A spring K is coiled on theouter end of the rod I and rests with one end on the bearing J and atits other end is engaged by a thumb-screw I, screwing on the extremeouter end of the rod 1 to regulate the tension of the said spring, andconsequently the pressure on the arm H and the disk II. The free end ofeach brakeblock E is provided with a lug E fitted to move in a guidewayor recess formed in the web of the wheel 13, as illustrated in thedrawlngs.

The operation is as follows: \Vhen the shaft A is rotated, the wheel Bmoves with it, and when. the speed of the shaft increases beyond anormal rate the weighted levers O swing outwardly by centrifugal force,whereby the brake-blocks E are moved in frictional contact with theinner surface of the rim F, so that a braking of the wheel 13 takesplace, and consequently the speed of the shaft A is reduced. WVhen thelevers O swing outward, the rods G pull on the disk H, so as to turn thesame in the direction of the arrow (1, whereby the arm H pulls on therod I against the tension of the sprink K, and when the speed of theshaft has decreased to its normal rate then the levers O swing inwardagain to move the blocks E out of engagement with the rim F, and thismotion of the levers is accelerated by the action of the spring K on therod I drawing the disk H back to its former position. It will be seenthat this device is very simple and durable in construction, can bereadily applied to various machinery, such as windmills and the like,and is not liable to get out'of order.

Having thus fully described our invention,

we claim as new and desire to secure by Letters Patent 1. An automaticfriction governor, comprising a fixed rim, a fixed part on the shaft orother movable part of the machine on which the governor is used,weighted levers fulcrumed on said part, brake-blocks pivoted to the saidweighted levers and part, and a spring-controlled device connected withthe said levers for accelerating the return of the same to a normalposition, substantially as described.

2. An automatic friction-governor, comprising a fixed rim,a plurality ofbrake-blocks, adapted to move in engagement with the inside of the saidrim, a part fixed on the shaft or other movable part of the machine onwhich the governor is used, levers fulcru med on the said part andpivotally connected with the said brake-blocks, a loose disk pivotallyconnected with the said levers, and a tension device for the said disk,substantially as shown and described.

3. An automatic friction-governor, comprising a fixed rim, a pluralityof brake-blocks adapted to move in engagement with the said rim, a wheelsecured on the shaft or'other movable part of the machine on which theon the said wheel and pivotally connected with the said brake-blocks, aloose disk concentric with the said wheel, links connecting a to returnthe same to a normal position, substantially as shown and described.

4. In an automatic friction-governor, the combination with a fixed rim,and a wheel mounted to revolve, of weighted levers pivoted to the wheel,and brake-blocks pivoted to the said wheel and levers, substantially asdescribed.

5. In an automatic friction-governor, the combination with a fixed rim,and a revoluble wheel having notches and guideways in its rim, ofweighted levers pivoted to the wheel, brake-blocks in the notches of thewheel and provided with lugs fitted to move in the guideways of thewheel, 'a link pivotally connecting the blocks to the rim of the wheel,and

- links pivotally connecting the blocks to the levers, substantially asdescribed.

6. In an automatic friction-governor, the combination with a fixed rim,a revoluble wheel, pivoted levers, and brake-blocks carried by thelevers, of a loose disk, an arm secured to the disk, a bearing on thewheel, a

, rod secured to the arm working in the said bearing and provided with athumb-screw at its end, and a spring on the rod between the bearing andthumb-screw, substantially as 5 described.

governor is used, weighted levers fulcrumed CYRUS MOORE. PERRY SAVILLEWVEST.
